Hey guys, I built this clock. I had a friend help me with the woodworking for the case. I used an Arduino board as the compute platform and designed and 3D-printed the display components using several LED strips. I wrote all the code.

It shows hours and minutes, metric time and the current decibel level.

Here’s a video of it working with the front open.

I’ll be givinga talk on the project on Friday, Mar 27 at 6pm at UQBAR cafe in Berkeley, which is where the clock is hanging. Stop in if you’re in the Bay! If you come by early, 5 or so, you can buy food and drinks. I’ve had a lot of fun with this project and look forward to talking about it!

@mikeolson I'll be there. Can't wait! Also, have you considered a Mayan calendar clock?

@cutting As a matter of fact...

I was in Central Mexico some weeks back and attended a few lectures on the region's history and people. I'm intrigued by the cyclic ceremonial and astronomical calendars that the Mayans developed. I have to think of a good way to present that data, but it's on my mind.

@mikeolson I've heard that Nixie tubes for the Mayan alphabet are hard to source.
